The battery shall be repaired, replaced or maintained by skilled personal recognized. (Skilled personnel recognized is a trained and qualified electrician or installer defined in installation guidance). Do not reverse the polarity. Do not stack up batteries without protective package, when store or handle batteries. Do not open, mutilate or disassemble the battery, the released electrolyte, which may be toxic, is harmful to the skin and eyes. Disconnect the charging source prior to connecting or disconnecting battery terminals, for instance, disconnect battery from power/load and then power off battery before installation and maintenance. Packaged batteries should not be stacked more than specified number stipulated on the package. Do not lay tools or metal parts on top of batteries. Do not use damaged, failed or deformed batteries, which may reach temperatures that exceed the burn thresholds for touchable surfaces. Continued operation of damaged battery may result in dangerous situation and cause severe injury due to electrical shock. 3 Technical Data Model Battery-Box H 5.1 Battery-Box H 6.4 Battery-Box H 7.7 Battery-Box H 9.0 Battery-Box H 10.2 Battery-Box H 11.5 Battery Module B-Plus H 1.28 (1.28kWh,24.7kg) 4 modules 5 modules 6 modules 7 modules 8 modules 9 modules Usable Energy 1 (kwh) Max Output Power(kW) Peak Output Power(kW) 10.24, 30s 12.80, 30s 15.36, 30s 17.92, 30s 20.48, 30s 23.04, 30s 1 Test conditions: 100% DOD, 0.2C charge & discharge at +25 C.
